Hello,
I can confirm the very same problem on my Thinkpad 420s (Sandy Bridge)
with the very same software and library versions. All versions of
related are up to date. This is my backtrace:
Application: KWin (kwin), signal: Segmentation fault

It's interesting to point out I /didn't/ have this problem until I
upgraded today. Before upgrading related package versions have been:
2011-11-22 00:32:14 upgrade libgl1-mesa-glx 7.10.2-3 7.11-6
2011-11-22 01:36:01 upgrade kde-window-manager 4:4.6.3-1 4:4.6.5-3
After upgrade:
kde-window-manager 4:4.6.5-3
libgl1-mesa-glx 7.11-6
